The corrosion inhibitors diminish during operation and lose their protective capability. Coolant that is too old, and has lost its important inhibitors
and anti-aging additives, becomes strongly corrosive. The coolant additives as under Sheets 311.0 and 312.0 will also age. This causes a
deterioration in the level of protection capability, and with regard to coolant refining agents this will also cause the emulsion to break down.
For this reason it is important to replace the coolant, in order to ensure that its corrosion protection capability is retained. If necessary the cooling
system should be thoroughly cleansed before refilling with the new coolant. A sufficient level of heat dissipation will only be given if the cooler
surfaces are clean.
The maximum permissible period of usage for coolant is cited in Overview Section 5.
Non observance of these regulations or the use of non-approved products will result in serious damage.
The use of approved operating fluids, which naturally include the anticorrosion/antifreeze agents, is a well-known constituent of the warranty
conditions.

Disposal of coolants
The coolants are biologically-degradable material. All statutory regulations or waste water regulations in each individual country with regard to the
disposal of used coolant must be observed. It is recommended to have the possibilities available for disposing of materials explained by the local
responsible water authorities.
Currently in Germany methods are being compiled for the purification of used coolant. The separate collection of all used operating fluids is
highly recommended.
However, as a consequence of the complex tasks asked of a modern coolant, it is on no account advisable to use an improperly "recycled" coolant,
which has only undergone a mechanical prepurification process.
